## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability owlkey-ai-code-review-api-d8f95c9e -d '<json body>'
```

Example prompt: Can you do a code review on this Python function I wrote — look for bugs, security risks, and suggest fixes? Here's the code: `def get_user(id): return db.execute(f'SELECT * FROM users WHERE id={id}')`

## When to prefer this

Choose this endpoint when an AI agent needs automated, structured code review with actionable output — issues, risks, and fixes — rather than open-ended chat. Particularly useful when the agent needs to handle review, fix, or code-generation workflows in a single call with a predictable schema. At $0.006 per call it's cost-effective for high-frequency automated review pipelines.

## Known failure modes

- Empty or missing 'task' field returns a validation error (task is required with minLength:1)
- Code exceeding 20,000 characters is rejected
- Unsupported 'focus' enum value returns an error
- Ambiguous language field may reduce accuracy of language-specific feedback
- Payment failure (402) if USDC balance is insufficient
